precise, so instead of just saying ok, we're going to target everyone that we know is, say, you know, a latino woman, you can actually individually start to target people based on what kind of car they drive or what kind of cereal they eat, all kind factors from when you fill out surveys or that kind of thing. the obama campaign did that even more impressive in 2008 and they've been building on that ever since, so they've built a formidable, digital integrated data targeting effort that they have put together with this vast network of field offices on the ground, and neighborhood teams and volunteers and through facebook and everything else. so they know practically who all of their voters are. the millions and millions of people that they expect or hope they can drive out to the polls to vote for obama. >> molly ball is a staff writer covering national politics at the atlantic, here to talk to us about the ground game for both candidates. you can read her work at the atlantic.com/politic. if you want to talk to her in person, pick up the phone, give us a call. 202-585-3881 for republicans. 20
